Why is Seaborgium in Period 7?

Let me ask you a question.

How many shells does a seaborgium atom have?

It’s 7. Right? 

You have already seen the bohr model of seaborgium atom in the above table.

From the Bohr model, it can be found that the number of orbits or shells in seaborgium is 7. Hence, as seaborgium has 7 orbits, it lies in period 7 of the Periodic table.

Why is Seaborgium in d-block?

Before knowing this reason, first of all I want to ask you a simple question.

How can you determine the blocks-wise position of elements?

The simple answer: The elements will lie in the s, p, d or f block will completely depend upon the subshell in which the last electron will enter.

For example; the electron configuration of seaborgium is [Rn] 5f¹⁴ 6d⁴ 7s². 

So the last electron of seaborgium enters the d-subshell or d-orbital. 

Hence, seaborgium is the d-block element.

5 facts about Seaborgium

Interesting facts about seaborgium element are mentioned below.

1. The element was given the name “Seaborgium” to honor the well known chemist Glenn T. Seaborg.
2. Seaborgium was discovered by Albert Ghiorso and his team (in 1974) at Lawrence Berkeley National Laboratory, California.
3. Seaborgium is a synthetic element which is not found naturally, but it is artificially created in a laboratory.
4. Seaborgium has around 12 known isotopes, and all those isotopes are radioactive in nature.
5. Out of all the known isotopes of  seaborgium, the most stable isotope is ²⁷¹Sg, which has a halflife of 2.4 minutes.
